  • Class:
    • A class is a recipe for an object (like a player or item). Classes can be extended to create child classes. A child class inherits traits of the parent while adding traits of its own. In biology ‘human’ would be a child of the class ‘mammal’. Child classes can also change some of the parent traits. If the class ‘mammal’ is defined as walking on land then the child class ‘whale’ changes that trait to swimming in water.

Actor Code

extends KinematicBody2D
class_name Actor

export var speed := Vector2(300, 1000)
export var gravity := 3000.0
var velocity := Vector2(0, 0)

func _physics_process(delta):
    velocity.y += gravity*delta
    velocity = move_and_slide(velocity)

Player Code

extends Actor

func _physics_process(delta):
    var direction := Vector2(
        Input.get_action_strength("move_right") - Input.get_action_strength("move_left"),

    velocity = speed * direction
